Symmetry-enforced stable zeros in exciton wave functions constrain relative exciton-band topology and relative band topology in 1D and 2D inversion- and rotation-symmetric two-band systems.
The Brillouin zone has high-symmetry momenta (HSM) atp ∗ = 0 andπ, which satisfyP p ∗ =−p ∗ =p ∗ (mod 2π)

Stable Wave-Function Zeros Indicate Exciton Topology
Symmetry-enforced stable zeros in exciton wave functions constrain relative exciton-band topology and relative band topology in 1D and 2D inversion- and rotation-symmetric two-band systems.
